sin(x) = 3/4
$$\sin{\left(x \right)} = \frac{3}{4}$$
Detail solution
Given the equation
$$\sin{\left(x \right)} = \frac{3}{4}$$
- this is the simplest trigonometric equation
This equation is transformed to
$$x = 2 \pi n + \operatorname{asin}{\left(\frac{3}{4} \right)}$$
$$x = 2 \pi n - \operatorname{asin}{\left(\frac{3}{4} \right)} + \pi$$
Or
$$x = 2 \pi n + \operatorname{asin}{\left(\frac{3}{4} \right)}$$
$$x = 2 \pi n - \operatorname{asin}{\left(\frac{3}{4} \right)} + \pi$$
, where n - is a integer

Rapid solution [src]
x1 = pi - asin(3/4)
$$x_{1} = \pi - \operatorname{asin}{\left(\frac{3}{4} \right)}$$
x2 = asin(3/4)
$$x_{2} = \operatorname{asin}{\left(\frac{3}{4} \right)}$$
x2 = asin(3/4)
